Then, this water is supplied to the water jet nozzle 34 again.

The armpit w which has passed the vicinity of the water jet nozzles 34, 34 reaches the vicinity of the air jet nozzles 40.
Here, the flow of the air jetted from the nozzle 40 and the flow of the air carried between the guide plates 11, 11 by this air flow are based on the guide action based on the shape of the guide plates 11, 11 on the side of the transport device 4. It is more converged, and the root side of the armpit w receives such an air flow above and below and effectively separates the adhered water.

After that, the armpit w is discharged from the other side surface portion a3 of the opening 3, reaches the end of conveyance of the conveyance device 5, and is positioned on the filter surface 9. At this time, the filter surface 9 removes the water remaining in the armpit w by the direct water suction action of the sponge material, and drops the armpit w to a specific position. The water sucked by the sponge material is guided by the guide tube 8.
It is returned to the inside of the water tank portion 1 through the inside.

During the above-mentioned peeling process, the endless pinching / conveying belts 5 and 5 continuously convey a unit amount of the armpit w, and each belt 5 is independently driven by another motor 6. Therefore, the sponge-like belts 5 and 5 do not extend unevenly, and evenly convey the upper and lower leaves of the armpit w to stabilize the leaves without damaging the leaves. It will be transported.
